IBM® xSeries 150 : User's Reference
Adding memory to your server is an easy way to make programs run faster. You can
increase the amount of memory in your server by installing options called memory-
module kits. Each kit contains one industry-standard, dual-inline memory module
(DIMM). Your server uses a noninterleaved memory configuration.
Your server comes with a dual inline memory module (DIMM) installed on the
system board in connector J23.
Notes:
1. Install additional DIMMs in the order specified in the documentation that comes
with your option. (See the following illustration for memory connector locations.)
2. Your xSeries 150 server supports 128MB, 256MB, 512MB, and 1GB DIMMs. Your
server supports a minimum of 128MB and a maximum of 4GB of system memory.
See the ServerProven list at http://www.ibm.com/pc/netfinity for a list of
memory modules for use with your server.
3. Installing or removing DIMMs changes the configuration information in the
server. Therefore, after installing or removing a DIMM, you must save the new
configuration information by using the Configuration/Setup Utility program.
When you restart the server, the system displays a message indicating that the
memory configuration has changed. Start the Configuration/Setup Utility
program and select Save Settings.
4. The illustrations in this document might differ slightly from your hardware.

To install a DIMM:
Attention: When you handle Electrostatic Discharge-Sensitive devices (ESD), take
precautions to avoid damage from static electricity. For details on handling these
devices, refer to the following Web site and use a search term of ESD:

1. Review the safety precautions listed in Statement 1 and Statement 5 in "Safety
information" on page 20.
2. Review the information in "Before you begin" on page 19 and the documentation
that comes with your option.
